Crash

BRIEF version
Taken over my shoulder, lying down. Air ambulance

Last summer, 4th July, I put myself in hospital. It is the subject of an Air Accident Investigation Report which will be published imminently. The BMAA magazine already let the cat out of the bag, for which they have apologised.

This will all be fairly humiliating. I don't come out of it well. The airworthiness of an aeroplane is the pilot's responsibility.

I took my wing off a few days previously to clean it. I got a very experienced friend, an inspector who has been around microlighting for many years, to help me re-rig the plane afterwards, as this was only the second rigging since I bought the plane.

As an SSDR aircraft it had been modified by the previous owner, who actually did a really good job of it. It is a good design, but you do have to remember what he told you about the process, and neither my friend nor I had remembered it. The front strut has two pins between the Jesus bolt and the pod. Because we hadn't unhooked the top one, we hadn't been able to slide the outer sleeve on the strut, so had found rigging the lower pin tricky, but finally my friend secured it, or so we thought. 

Actually, the non-sliding sleeve covered the fact that my friend had failed to pass the pin through both the inner tube and the outer sleeve, so that the top half of the front strut was not secured to the bottom tube; the pin was sitting on top of it. I explained it better in my crash report (will look it out). The point is that the mistake is not visible, as the connection is covered by the sleeve. A conventional front strut does not have the sleeve, so the error would have been obvious.

When I took off, the wing lifted, gravity came into play and the front strut separated and swung from the Jesus bolt. I performed an emergency landing in crop, only just managing not to get impaled on the exposed strut anchoring point which was sticking up towards me. The trike folded over my back and the monopole broke over my arm.



I managed to get out and go and lie a safe distance from the trike, while some friendly hang glider pilots who had witnessed the whole embarrassing thing called the ambulance. Unfortunately I wasn't in a bad enough state to go for a free helicopter ride, but had to wait for the ground ambulance to pick me up. Nothing was broken, fortunately. I just needed strapping up etc.

But there is little left of the plane...except, very happily, the wing, which is ok. I am building a new trike, about which, more later.
